FLUID-GAGE.

Application filed December 30, 1916.

To all whom it may concern:

Be it known that I, M. MAUmoE DrMoND, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved of which the following is a full, clear, and exact description.

My invention relates to fluid gages particularly adaptable for use in connection with gasolene tanks employed on motor vehicles.

An object of the invention is to provide a simple, inexpensive and efficient indicator Specification of Letters Patent.

which can be manufactured a't compara tively low price.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a section through the container provided with a gage embodying my invention;

Fig. 2 is an enlarged sectional view through the plug showing the indicator in locked position; and

Fig. 3 is a plan view of the plug.

Referring to the drawings, 4 is a container for liquid. It has an interiorly threaded collar 5 into which fits a plug 6. The plug has a recess in the top divided by a diametrieal ridge 7. The ridge is enlarged in the central portion, as shown at 8 and bored to accommodate a stem 9. The bottom of the plug has preferably a collar 10 which forms a guide for the stem at the plug. The stem 9 at one end thereof has a valve head 11 to fit snugly a tapering seat 12 formed on the central enlargement of the ridge. The

the p rpose Patented June 2?), 2. Serial No. 139,746.

The other end of the stem is anchored to a cork float 13 by making a tight fit between the bore in the float and the tubular member, and by coating the tubular member with shellac before forcing the same into the float, the shellac cementing the tubular member to the float. This provides a cheap and sure way of securing the float to the tubular member. The tubular member has a plurality of perforations 14 which serve as indicating means for the gage. Normally the head 11 of the stem 9 is maintained on the seat 12 against the buoyancy of'the float by a yielding member 15 in the shape of a flat spring, one end of which is anchored by means of a rivet 16 to a projection 17 formed within the recess of the plug 6.

The movement of the spring is limited by shoulders 18 which are formed by depressing the central portion of the ridge, as has been previously mentioned. The de pression in the ridge to each side of the bore is suflicient for the sprim to clear the valve head. The top of the head is preferably slightly curved to facilitate the engagement of the spring with the head when the float is forced into the liquid body to lock the valve on its seat.

I claim:

A liquid gage comprising a plug having a recess in the top thereof, a diametrical ridge in the recess presenting an enlarged portion having a central aperture, a tubular stem fitting into the aperture and presenting a tapering valve head at one end thereof, said central, enlarged portion of the ridge presenting a tapering valve seat at the aperture for said head, said valve seat being depressed from the surface of the ridge, a tubular extension from the bottom of the plug serving as a guide for the stem, a flat spring anchored to the plug within the recess for engaging the valve head of the stem to retain the same on the seat, and afloat anchored to the stem.
